ZL9024M Datasheet | Renesas

Digital DC/DC PMBus 33A Module The ZL9024M is a 33A step-down DC/DC power supply module with integrated digital PWM controller, synchronous power switches, an inductor, and passives. Only bulk input and output capacitors are needed to finish the design. The 33A of continuous output current can be delivered without a need of airflow or a heatsink. The thermally enhanced HDA module is capable of dissipating heat directly into the PCB. The ZL9024M uses Charge Mode™ control architecture, which responds to a transient load within a single switching cycle. The ZL9024M es with a preprogrammed configuration for operating in a pin-strap mode; output voltage, switching frequency, and device SMBus address can be programmed with external resistors. More configurations, such as soft-start and fault limits, can be easily programmed or changed using PMBus pliant serial bus interface. PMBus can be used to monitor voltages, current, temperatures, and fault status. The ZL9024M is supported by Power Navigator™ software, a Graphical User Interface (GUI) that can be used to configure modules to a desired solution. The ZL9024M is available in a 40 Ld pact 17mmx19mm HDA module with a very low profile height of 3.55mm, suitable for automated assembly by standard surface mount equipment. The ZL9024M is Ro HS pliant by exemption.
